HOSE.

Specification of Letters Patent.

Patented Nov. 2, min.

Application filed November 15, 1912. Serial No. 731,516.

To all whom it may concern Be it known that I, JOHN J. VOORHEES, J r., acitizen of the United States, residing in Jersey City, county of Hudson,and State of a New Jersey,'have invented certain new and usefulImprovements in Hose, of which the following, taken in connection withthe accompanying sheet of drawings, forms a full, clear, and concisedescription.

My invention relates to certain new and useful improvements in hose, theobject being to provide an article of this kind which will be'flexibleand convenient for use, while at the same time rendering it durable andable to withstand long and severe service conditions.

My invention may be applied to various uses, but one form of applicationwherein it is especially useful is illustrated in the ac- 2o companyingdrawings, and which consists of an armored hose such as is used for manypurposes in the arts.

In these drawings, illustrating one form of my invention, Figure 1 is aside elevation of a piece of hose shown partly in section. Fig. 2 is, anenlarged cross-sectional view of the wall of the hose; and Fig. 3 is aview, partly in section of a piece of hose showing it bent and subjectto the strains which ordinarily are extremely injurious to an article ofthis character and construction.

In the drawings, the numeral 1 indicates the tubing proper, which may beof rubber or other suitable flexible material. 7

The numeral 2 indicates diagrammatically layers of reinforcing fabricwhich may'or may not be used. 1

The inner side of the tube comprises a lining 3, of fabric, and areinforcing element 4 to (which in the form illustrated consists of aspirally Wound flat metal band), is provided to assist in maintainingthe true form of the tube, and also forms a reinforcing and wear,-resisting element which greatly adds to the at strength and durabilityof the 'hose.- Hose of this general character have been used for sometime but have only been partially satisfactory, largely by reason of thefactflthat when the hose is bent the spirally-arranged to reinforcingmember is apt to be displaced and slip and thereby-cause cutting orinjury to the tubing and also a permanent distortion of the hose.

M tion of the reinforcing element so thatthey will not become displacedunder any ordi- I have therefore found it extremely desirable to anchoreach convolunary service conditions to which the hose is sub ected, nomatter how much or in what manner it may be bent, and the preferable wayI have found is by providing pro ections from the inner surface of thetube substantially equal in width to the space between the convolutions,and in the. form of the metal, as shown in Fig. 2. After thisv therubber tube is formed upon the cord and fabric and the tube may bevulcanized, coated, or treated in any way desired.

It is obvious that many modifications and changes may be made in detailsof construction and arrangement without departing from the spirit of myinvention, and also other methods of construction may be employed, and Ido not mean to limit myself to those specifically shown and described.

Having thus described my invention what I claim new herein and desire tosecure by Letters Patent is 1. A hose having a smooth outer surfacecomprising a tube of rubber, a fabric lining for the interior of saidtube, a reinforcing element of flat metal spirally wound within saidtube and lying upon the inner. surface of said fabric, and means foranchoring said reinforcing element within said tube, said meansconsisting of a cord spirally wound about the outer surface of saidfabric contiguous to the spaces between the convolutions of thereinforcing element, whereby a plurality of inwardly projecting ribs areformed within th'espaces between the convolutions in the reinforcingelement, the edges of the fiat metal abutting thereagainst.

2. A hose having a smooth outersurface comprising a tube-of rubber, afabric lining positioned therewithin, a reinforcing element of flatmetal spirally wound and arranged within said tube, the convolutions ofios the reinforcing element bearing upon the inner face of said fabric.and means for anchoring the reinforcing element within said tube, saidanchoring means comprising a cord spirally wound about the outer surfaceof said fabric adjacent tothe spaces between the convolutions of thereinforcing element, whereby a plurality of inwardly directed protectivespiral ribs are formed by the cooperation of said fabric and saidanchoring 00rd,. said ribs projecting through the spaces between theconvolutions of the reinforcing element and extending a considerabledistance inwardly beyond the plane of the inner faces of theconvolutions of the reinforcing element, the reinforcing element andfabric being thereby securely locked against relative longitudinalmovement.

3. A hose formed of a strip of spirally wound fiat metal, having a tubeof fabric disposed thereupon, a cord spirally wound upon the outersurface of said fabric to form ribs projecting inwardly in theinterstices between the convolutions of said fiat metal strip, and atube of rubber applied to and lying in close contact with the outersurface of said fabric, the formation of said ribs serving to hold theres ective convolutions of the metal'against movement relatively to eachother and at all times maintaining the metal out of contact with therubber and preventing injury thereof.

In witness whereof I have hereunto set my hand in the presence of twosubscribing
